To all whom it mayconcern:

Be it known that I, ARTHUR E. FRANCIS, a citizen of theUnited States,residing at Cleveland, in'the' county of Cuyahoga and State ofO11io,'l1ave invented certain new and useful Improvements in ElectricSwitches, of which the following is-a specification. v v This inventionrelates to electric switches, and particularly to'aswitch adapted to beattached to the steering post of an automobile. The location of a'switchon a steering,

post, just above "the steering wheel, is very convenient foroperation byeither hand of the driver, and the objectof the present inven-tion is toprovide .an improved switch which may be quickly and easily mountedpost, in the position indicated The device is especially designed forthe Ford automobile, but may be'used on other machines with little or nomodification.

The accompanying drawing is a vertical section'of the switch, showingthe same applied to the steering post of an automobile.

Referring specifically to the drawings, 1 indicates, the steering postand 2 the steering wheel secured thereto by a nut 3 which screws on thethreaded end of the post.

The switch casing is indicated at 4, and is preferably made of metal.The upper end 7 of this casing is circular, and the lower end 5 ishexagonal, to fit closely over the nut 3 to which it is fastened byscrews 6 fitting tapped holes inthe sides of the nut. Obviously theshape of the casing may be varied to fit the nut-son knobs of, varioustypes of steering posts.

7 Within the casing is a block 7 g of insulat ingmaterial which hasrecesses on the underside and rests on thetop of the nut 3.

Aspring contact piece 9 is mounted-on top of the block 7 by a rivet 10which is connected toa binding screw 11 by a small plate 12, and thescrew .11 also connects the wire copies of this patent may be obtainedfor Specification of Iietters Patent. 7 j Patented May 20, 1919,

13 leading to the horn or -other signal not shown. .Another contactpiece 15 is held on top of the block by a rivet 16 and con nected by asmall plate to the binding screw 18 which may be grounded or connectedto a ground wireif two wires are used. The contact piece 15 has adownwardly projecting arm 15 which connects to the fastening screw 6,which forms a,

and is held therein bya flange 23 at the 'upper edge, by a rivet 24. iThis rivet 24 rests on the, spring 9 which normally acts to hold thebutton in raised position with the contacts open.

When the button is pressed down the contacts 9 and 15 are closed, toclose the circuit and operate the horn or other device. I

The switch can be easily applied to or removed from the steering post,and is supported in a very convenient .position for the. operation.

I claim: v The combination with a steering post having a nut at the topthereof, of a switch comprising a shell shaped to fit around and inclosesaid nut, a block resting on the nut and confined thereto by the shell,contacts supported bythe block, and a push button mounted on the top ofthe shell and ar ranged to close the contacts.

In testimony whereof, I do aflix my signature in presence of twowitnesses.
